The betta fish is one of the most popular and most misunderstood freshwater species. This guide covers everything from proper tank size to the truth about tank mates.
Maintain these water conditions for optimal health and vibrant colors
Bold Nemo marbling — orange, red and dark patches in koi-style blocks — on a female from the giant line: that is this 6.5 cm fish in a sentence. Giant-line females carry more body than standard females, giving the Nemo patterning a broader canvas, and her marble genetics mean the blocks will go on shifting subtly throughout her life. The fish you photograph in six months will not quite be the fish you unboxed.
She is semi-aggressive and moderate care, with a short approved-company list: small peaceful snails, plus peaceful shrimp in heavily planted tanks where hunting remains possible. Her exclusions name other bettas, fin-nipping species such as tiger barbs, aggressive or highly territorial fish, large predators, and fast boisterous tank mates that stress her. Space her from 20 litres at 24–30 °C, pH 6.0–7.5, hardness 1–15 dGH — undemanding numbers any heated aquarium can hold. Feed a carnivore diet to keep the orange blocks vivid, expect her in the top region of the tank, and allow for the territorial spells her record flags around breeding condition.
Giant-line females eat like the bigger fish they are, so portion her carnivore feeds above standard-female amounts and let body condition guide adjustments — a well-covered Giant Nemo female has visible substance without a swollen profile. Her 20-litre minimum is comfortably exceeded by most setups, and more volume slows the chemistry swings her marble colouring makes you watch for anyway: pattern drift is normal, washed-out colour is a water signal. Keep 24–30 °C on the heater, pH inside 6.0–7.5, hardness inside 1–15 dGH. Her semi-aggressive grading mostly sleeps when she is kept with snails alone, surfacing — as her record notes — around breeding condition, when even placid females remember what species they are.
No two Nemo females match, and we make no attempt to pretend otherwise — the marbling you receive is unique to your fish. Insulated UK shipping by licensed live-animal courier, live arrival guaranteed.
